Having thus given a general statement as? the character of my invention m cead to a. 1etai1 tlescripiion fiheraog T61 de to the drawings in Wh Emmi; a sugwortmg Wp-Q the mechanism. Extending upwardly from the bed 11 of the frame is a pair of forwardly projected standards 1:2 carrying the power driven impression cylinder or platen 13, the latter being held by the standards over the bed. at a point near the feeding end of the machine. The cylinder 13 driven from the inain power shaft ll through the intermediary of the gear train 13. 16, 17 and 18, the last mentioned gear being fixed on the shaft 19 to which the impression cylinder is fixed. Fixed upon the shaft 1% is a pulley 20 which is belt driven from any suitable source of power.

Extending lengthwise of the bed 11 on.

the upper face thereof is a pair of guide rails or tracks 21 on which a carriage, designated generally as 22, is designed to have limited reciproc'atcry movement. Depending from the lower face of the carriage at nearly the median part thereof isan arm or bar which is adapted to be engaged by the cam lever 24: fixed to the shaft 25, the latter being rotated from the shaft 1 through the gear train 15. 26, 27 and 28. The direction of rotation of the gear Wheel 28 is indicated by thearrow M in Figs. 2 and 3, and at each revolution of the wheel '28 the convex edge or face of the lever 24c engages and acts against the bar 23 and prevents forward snapping of the carriage under the action of retractile springs as more fully hereinafter described.

Fixed to the lower end of the carriage 22 and extending longitudinally thereof at approximately its middle line is a rack bar 29, the teeth of which are designed to mesh with the teeth of a. gear wheel 30 loosely mounted on the pulley shaft 14. The gearwheel 30 is solid except for a. recess 3% formed t1. 01D, and fixed to the shaft 14-.

adjacent th Wheel 30 is a hub 33 (Figs. 10

and 11) carrying latch arm 34: provided at its free end with a-pivotecl latch normally pressed toward the wheel 36 by means of the spring 86. The latcharm 34., constantly; tates with the share; 14. as it is fixed to"t J latter, lout the gear wheel 80 is not revolved (it.. being loose'on the shaft 14:) until the late-M is pressed into the recess 32 and then both arm 34. and

wheel 30 rotate together in the direction bf arrow Y (Fig. the rotation continuing until. the hooked end of latch 35 is tripped out of the recess 32, by a bent plate 3? fixed to a suitable part of the bed 11. At this time the cam lever 24.- has been moved into Isabstantially horizontal. position by the continucd rotation of shaft 25, and said lever'is imposition to engage the arm 23 and'control'the retractile movement of the carriage. When the'carriage has completed its rearwardtravel under the action of the latch 35 engaging in. the recess 32', the carriage is retracted to initial position by pair of' fairly powerful coiled springs 31, which have been tensioned during the rearward movement of the carriage each spring having one end thereof attached to the rear end ofthe carriage and its other'end attached to a point near the forward end of the machine frame 10. [is the pull of these springs is power"- fu-l the carriage would he likely to snap forwardly at a greater speed than its rearward travel, unless means to prevent this he provided. To prevent such forward snapping of the carriage and the attendant danger of damage to the machine, and to cause the speed of forward and rearward travel to be uniform I provide the coacting lever 24 and arm 28. The lever 2 holds the arm 23 for 'a barely appreciable space of time, while the latch is being freed from the recess 32, and then the convex surface of the lever 24: glides over the face of arm 23 and thus causes the carriage to glide smoothly and easily back to initial position under the action of the retractile springs.

Secured to and extending transversely of the carriage 522 near its forward end is a pair of spaced tracks or guides 38 (Fig. 5)

for the galley designated. generally as, and illustrated in '7 and 8. intermediate the tracks 38 the carriage is provided with a groove or depression etOserviing as a path for the travel of an endless chain 41 which passes over sprocket Wheels 4-2 and 4-3 (Fig. t) fixed, respectively, on the revoluble shafts 4e and 45, the shaft 44 being supported by the tracks 38 below the plane thereof, an the shaft 45 being supported at the opposite end of the carriage 22, below the plane thereof. Gne of the track members 21 is provided with an elongated slot 21* to allow for the rotary and longitudinal travel of the chain 4:1.

The preferred form of galley for receiving the type forms 4-8 (Fig. 3) is preferably trough shaped in cross section, its lower face being grooved out at 49 to provide clearance for the chain 41. The lateral faces of the galley are slotted at 50 to engage, and he guided by, the tracks 38 in the reciprocatory carriage,22. Near one end, the forward end, the galley is provided with a pivotally mounted cross pin 51, having a central stud 5:2 adapted'to engage the links of the chain ll tinder certain conditions, and a lateral arm 53 designed to abut against the Wall of a slot as (Fig. 5) formed in the csrri 'Both stud 52 and a n 53 extend an, angles to the longitudinal axis of the cross pin, but the stud and arm agfe'arrange at an angle of substantially 45 degrees toeaeli other, so that when the arm 53 hitsagai'nst' the edge of the slot o ithi's arm will rotate the pin 51,,ahout its. own longitudinal axis whereby til-3 arm, will heturned: into liorin zontal position While the stud will moved into the position shown in Fig. 8, that is per- A 12* m, and in cmuiiixon be. engaged 1' uche "(l ca-{ip .E'Zlfii! file aha 3 spring paw ff 'wm'dly P Y ate the spuoIs-z at each re awn-via;

The pad 88 is removable and the particular pad used at any time as wide as the type form then. being used is long. The opening 86 in the feed hoard adjustable as to size by means which it has not been deemed necessary to, show or describe.

In the foregoing description l have, in a. general way, outlined the operation oi cer tain parts or snbcon'ihinatione of the machine, and I will now proceed to describe the operation of the entire mechanism.

Assuming the pulley 20 to be revolving, the impression cylinder will rotate as will also the shaft 25 carrying the cam lever 24. Assume further that a galley with type forms has been properly positioned so that the stud 52 is engaged by the links of the chain 41, and that an envelop, for example,

has been fed to the board 85. As the gearing revolves the carriage with the galley are drawn rearwardly. The envelop, or other article to be printed upon, is drawn inwardly by the impression cylinder and as the type form with its superposed ribbon is moved to apoint directly under the orifice 86, the cylinder will cause a printing impression to he made on the envelop and the latter is dis "charged at 87. The carriage is then retracted, and in this retractilq movement the worm 55 glides in the guide plate 56 causing rotation ofthefratchet wheel, 62 and consequent forward feed of the galley, whereby the type form immediately following that printed fr L is placed intov printing nosition.

It is'ioi conrse understood that galley after igalleyi'of type niafbefemployed, the operation of the machine being continuous, and its speed being limited practically only. by

- the speed imparted to the pulley wheel 20,
